Application filed August 22, 1890. Serial No. 362,762. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR L. HUMPHREY, a citizen of the United States,residing at Colorado City, in the county of El Paso and State ofColorado, have invented certain new and useful Improvements inCar-AxleBoxes; and Ido hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part ofthis specification, and to the lettersof reference marked thereon.

This invention relates to certain new and useful improvements incar-axle boxes; and the novelty resides in the peculiar co1nbinationsand the construction, arrangement, and adaptation of parts, all as morefully hereinafter described, shown in the drawings, and thenparticularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure 1 is a vertical longitudinal sectionthrough a car-axle box embodying my invention. Fig. 2 is a front view ofthe same with parts broken away and others in section. Fig. 3 is a frontview of the end-thrust block removed. Fig. 4 is an edge view of thesame.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates acar-axle box of ordinary construction except as hereinafter specified.It is formed upon the under face of its top with a shoulder a, whichprevents end movement of the upper block B, the front end of whichstrikes against said shoulder, as shown in Fig. 1. ,At the front end thebox is formed interiorly with vertical ribs 1), which have a horizontalshoulder c, as seen in Fig. 1, and against which the end-thrustblock Crests, as shown in the same figure.

B is the bearing, and E isaring of asbestus or any other suitablematerial surrounding the same at the inner end of the box in the usualmanner.

F is a block fitted to the journal and resting upon the upper sidethereof. Itis formed upon each side with a lug'e, which engages verticalribs 01 upon the inside of the box, as

shown best in Fig. 2. This prevents endwise movement of the block. Theblock 13 is fitted to the upper face of the block F, and at its rear endengages a lug f on the said block F, as shown in Fig. 1, and thus thetwo blocks are prevented from endwise movement in either direction, theone helping to hold the other.

The end-thrust block C is formed with a central circular portion, asshown in Fig. 3,

against which the end of the journal ,is de-' signed to contact, andwith depending legs or upon the under side of its top, of the block F,

fitted to the journal and formed with side ribs and lug atits rear end,the block B, fitted to the block F and engaging the end lug and theshoulder a, and the end-thrust block, substantially as and for thepurpose specified.

2. The combination, with the box formed with central and side ribs 1),having shoulders c, of the end-thrust plate or block formed withcircular portion bearing against the central rib, and depending legsresting 011 the shoulder a, substantially as specified.

3. The combination, with the box formed with vertical central and sideribs 1) and shoulders 0,.of the end-thrust block formed with thickenedcircular portion and depending legs, the central one of which isthickened, with passage-ways between the legs, substantially as shownand described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
